This is a mini band set from Perform Better. It's a set of four training tubes in different colors, suitable for various types of training. I recently bought them to work out at home, but I couldn't keep it up, so I'm selling them. Only the green band has been used, and it was used five times. The others are unused, but they have been stored at home, so please understand.
